Data Changes

Two dose forms have changed for the June release. Enteric Coated Capsule is now Delayed Release Oral Capsule, and Enteric Coated Tablet is now Delayed Release Oral Tablet. Concepts using the old dose forms have been updated with the new dose forms. RXAUIs for these terms have changed, but their RXCUIs remain unchanged.

Effervescent Oral Tablet was added as a dose form. This dose form is defined as: a solid dosage form containing mixtures of acids (e.g., citric acid, tartaric acid) and sodium bicarbonate, which release carbon dioxide when dissolved in water; it is intended to be dissolved or dispersed in water before oral administration.
